I dropped my coolant, have to flush and refill before winter gets here. Any tips to avoid getting an airbubble in the system? I remember something about running it while refilling it and having the nose up...? Cant remember.

hammer1 said:ive put a little peice of 3/8 hose through the fill cap, and into the body of the rad.
that way , i can use a funnel , and not have the burping issue.
NocalFJ60 said:There is just the chance air pockets are in the cooling system. The air pockets do not allow cooling of the wall there so you get hot spots.
hullendersauce said:what do "hot spots" do? should i flush and fill again? about a month ago, before winter hit, i wanted to flush my radiator, and refill. well, i did exactly what the bottle said. but i just threw a hose on it, and filled it throught the top of the radiator. i ran it for awhile, and then topped off my reservoir. should i go back and drain it again??? i just dumped a crap load of $ into it, hoping it would get me throught the winter ok. i dont need any unnecessary problems with the upcomming winter. -other sean
